Tokugawa Iemitsu had already issued an order to summon all the feudal clans to come to King Koto.

However, half a month has passed, and in addition to a few daimyo who have a relationship between and the Tokugawa family, there are hundreds of daimyo such as the Okuwa Domain, the Chugoku Domain, the Tokai Domain, the Kanto Domain, and the Koshinkoshi Domain, and none of them have arrived!

Tokugawa Iemitsu knew that the so-called wall fell down and everyone pushed it, and these princes were watching from the wall, hoping that the shogunate would be defeated by the Ming army, and they would be free!

Over the years, the Tokugawa clan relied solely on "arbitrary politics" to suppress the daimyo of the feudal domains, so that those who had been hostile to the shogunate were either exterminated or submitted.

However, this is all superficial, and once the shogunate encounters a strong enemy, these daimyo are already very restrained if they do not stab them in the back.

What made Tokugawa Iemitsu depressed was that the shogunate sent a letter of state to the Qing State, but there was no trace of them, could it be that they were afraid of the Ming army?

On beaches, ports, water gates and other places, the soldiers and samurai of the shogunate were armed with spears, katanas, bows and arrows, iron cannons and other weapons, as well as a small number of artillery, and were ready to block the landing of the Ming army.

Tokugawa Iemitsu was a little relieved, Edo was not a Yokosuka fort, although the warships of the Ming army were huge, but after all, they were at sea, and it was probably not so easy to break through Edo's city defenses!

However, their strength is still very strong, and it is an unwise choice to fight such an opponent, and after repelling the Ming army this time, the shogunate should send someone to continue to make peace with them earlier......

In the middle of his thoughts, Tokugawa Iemitsu saw a huge smoke suddenly rise from the Ming army fleet in the distance, and it flew out of the visual range of the telescope in a flash.

Tokugawa Iemitsu was startled, and hurriedly put down the binoculars and watched with the naked eye.

I saw a long cylindrical object streak across the sky, with a sharp whistling that tore through the air, and a puff of flame and a long smoke trailing its tail, flying towards Edo Castle at a very fast speed.

The officials, samurai, and miscellaneous soldiers of Edo Castle, as well as the residents of the castle, also spotted the strange flying object, pointed in shock, and muttered to themselves with their mouths open.

Tokugawa Iemitsu is also curious, what is this whistling thing?

In just a few breaths, the long cylindrical flying object began to dive in a falling position, almost grazing the walls of Edo Castle and shooting into the castle at once.

"Boom!"

With a loud explosion, there was a violent explosion in Edo Castle, and countless scattered sparks fell on the surrounding houses, and the flames gradually spread over the nearby houses.

Tokugawa Iemitsu and other shogunate officials were shocked, Edo Castle was three or four miles away from the Ming army's warships, what kind of weapon was this, it could fight so far!

A chill suddenly appeared behind Tokugawa Iemitsu, if the Ming warships got closer, I was afraid that they would be able to hit the castle tower, or cover the entire Edo Castle!

On the battleship Tianquan, the flagship of the Ming army, rows of rocket launch slot brackets were lined up on the deck, and the various units of the rocket battalion had been prepared.

"Report to Shen Shuai, the second-generation Dongfeng rocket test launch was successful, and the rocket battalion is all ready!"

Shen Shouchong nodded slightly, without any expression on his face, and spit out a few words sonorously: "Dongfeng rocket, all out!" ”

"Yes!"

The head of the rocket battalion turned pale, turned around and shouted: "Target Edo City, Dongfeng rocket, launch!" ”

"Launch!"

The rocket captains of the rocket battalion groups shouted in unison.

As the fuse ignited, the sparks shot in all directions, and the rockets hissed and burned.

After the fuses were burned, thick flames suddenly erupted from the tails of each rocket, and large puffs of smoke poured out, enveloping the surroundings of the launch slot.

One rocket after another soared into the air, dragging bright flames and tearing through the air, whistling towards their respective targets like meteors.

"Launch!"

"Launch!"

The deck of the Tianquan was already filled with gunsmoke, but a large number of rockets continued to be launched.

In addition to the Tianquan, the main battleships such as the Tianxuan, Kaiyang, and Jinwu all launched second-generation Dongfeng rockets.

The Ming army used the second-generation Dongfeng rocket, which had the longest range, which was modified by Dongfeng Boli Dongfeng on the basis of the Dongfeng rocket in the first generation.

The second-generation Dongfeng rocket is larger, has more charge, has a longer range, and is more powerful, and requires a special launcher to be launched, which is only for the use of the navy.

At present, the Ming Royal Navy is only qualified to equip sail battleships above level 4, and the number of battleships carried by each battleship is also limited.

The maximum range of the second-generation Dongfeng rocket can reach about three kilometers, which is one kilometer more than the first-generation Dongfeng rocket.

However, the accuracy is average, and it cannot be used to attack the enemy's warships, but it is very useful for sea and land attacks, especially when doing unbiased attacks, it is absolutely powerful!

Since the development of the second-generation Dongfeng rocket, it has only been tested many times, and has not been used in actual combat.

Hundreds of second-generation Dongfeng rockets fired in a salvo, and they dragged a long tail flame into the sky, and the sky was full of long fireworks tracks, as if it had rained meteorites, burning the entire sky!

"Here we are, here we go again!"

There was an exclamation from Edo Castle, everyone shouted in horror, and even Tokugawa Iemitsu, the always calm general of the expedition, changed his face drastically.

Rockets rained down like meteors falling from the sky, descending over Edo Castle.

The Japanese in the city, rich and poor, were all in chaos, and countless people ran and roared, which made them feel hopeless and overwhelmed by unprecedented power!

In the midst of a terrible whistling sound, hundreds of huge rockets fell into the city, causing an explosion, and the entire Edo Castle trembled instantly!

In a series of explosions, a surging wave of air filled all directions, and charred corpses were everywhere.

The grease contained in the rocket also scattered and splashed in the city with the explosion, and the houses, streets, and trees were all wreaked havoc, and the flames in the city were lit and red, like a cloud of fire.

One of the Dongfeng rockets landed less than 100 meters away from the castle tower, and Tokugawa Iemitsu was so frightened that he took several steps back, only to feel his mind buzzing.

Seeing the surrounding shogunate officials dodging in terror like headless flies, and the elder shouting at him, Tokugawa Iemitsu was sweating profusely, his face was like ashes, and he muttered, "What kind of weapon is this......

Originally, he still had a glimmer of hope to expel the Ming army, but he didn't expect this to be the result.

Not only was Edo Castle attacked by the Ming army, but the defense line on the shore was even worse under the guns of the Ming warships, and there were bloody corpses everywhere, as well as fragments of armor and flags scattered everywhere.

The shogunate army was in complete disarray, and countless men and horses were running and roaring.

This absolute power terrified them from the inside!
